That was a weapon that formed its blade out of energy just like the ones he saw during recess.

Shinichi figured it was probably a simpler version of it as he thought back to Falandia.

“They had weapons like these back there too, weapons that made its blade out of mana.”

Such weapons had the advantage when it came to portability and durability, but having to use mana as fuel made them unpopular in Falandia. Molding mana into a weapon might have been possible, but no one really wanted to do it. After all, wasn’t Earth the same? Hardening gasoline and shaping it into a weapon might be possible, but no one would actually bother.

If a weapon was needed, then it was better to just use mana the proper way. Of course, sometimes the mana cost was too high, but that’s another story.
